T all whom it may com ""2:

Be it known that .l, lViLLiAM F. Ko an, a citizcn of ihc Uniiod States, residing at Newborn, in the county of Ur :fll and Stziic of North Carolina, have. invented certain now and useful. linpi'ovcnicni's in Applioncos for Sawmill L t il oriis, oi which iiho following a, sncci'li itiPIi.

Myinvvntion wishes to saw-mill sci. works and. more particularly in :in zipplhin e for socuiciy holding tho I shziii from moromcnt unlcss i'clouscd by rho operator.

in tho nccoinpnnying drawing forming, a part ()i illy invention l lnwo shown in improveincni upon :1 portion of :1 sec shaft, the remainder of tho mechanism comprising the set works, such as tho linocsinnd the menus for roccrlii'ig the some. noi, being included as the some are. so wcli known in ihc or; and are ihorcfoi'c unncrcsszn'y.

In the pro-chi l UD'lbCQiTRBDlZ oi niy invention'i provides sink Wheel 1 mounted upon the shaft C and having 2:, two part operat-- ing hand brake 2 comprising sections 3 and 4 hingedly sonncctcd at 5, ossocintcd upon its periphcry hoving an operating lover (i pivotally conncotcd 7 to the free end of section 4. The section to said bra-kc 2 is provided with a straight integral portion 8 extending therefrom approximately parallel ith the lover 6, and between which and said lever 6 is arranged connecting chimps 9 form- :uvings, A

Yiow inlion 17 and ononinir the l.lI'iLi ing a pivot; for the operating lever 6 toward the portion 8 as will be seen, the sci screw 10 arranged through iilic upper end of said poibion 8 operating to limit saidmovement.

Mounted adjacent the operating lower 6 is s qnsdrzint 11 carrying on outstanding stud 12 against which said. lever is adopted. to rest, olmrohy nornia-liy hoichng the hand bi'slro 2 we and oui of clutch with the wheel 1. A inilsr hrslio 13 is also raised upon the when] 1 comprising the sections A and 15 hingodly connectcd M16 and having 1% lever 17 pivoi'nily connoctcd {Ll its cnds to the free end 15 of the section l5, and to an upstanding rigid bracket W nionnoed. up he oarringo i i-sine A. The section l ll 1 )i'olrc l3 providcd with. straight. iii "iii secsions i 17 sic conat 272 a for tho lever 17 whoroliy the v. ighl; of
